When it feels absolutely hopeless...

How do you cope? Been ttc for the past 3-4 years. We know what the issue is. Have been told our only option is IVF. We can't afford IVF. So we just have been taking supplements. I thank God that I already have a beautiful 9.5 year old daughter from a previous relationship. My husband has just about zero motility. I found out yesterday that my sister is pregnant with her 3rd baby. Complete oops. She said that he didn't pull out and she even took the plan B pill and it still failed. Just hurts to see people get pregnant so easily. 😕

I can't help but be bitter. I'm so happy for her but so sad. How do you all cope with your struggle?
